Split a folder into multiple subfolders in terminal/bash script

Try something like this:

for i in `seq 1 20`; do mkdir -p "folder$i"; find . -type f -maxdepth 1 | head -n 2000 | xargs -i mv "{}" "folder$i"; done

Full script version:

#!/bin/bash

dir_size=2000
dir_name="folder"
n=$((`find . -maxdepth 1 -type f | wc -l`/$dir_size+1))
for i in `seq 1 $n`;
do
    mkdir -p "$dir_name$i";
    find . -maxdepth 1 -type f | head -n $dir_size | xargs -i mv "{}" "$dir_name$i"
done

For dummies:

1. create a new file: vim split_files.sh
2. update the dir_size and dir_name values to match your desires
   • note that the dir_name will have a number appended
3. navigate into the desired folder: cd my_folder
4. run the script: sh ../split_files.sh
